Finding my (electric) wheels

I have a Volt bike with a C2 controller and rear wheel motor (same computer is also on a Blix / Ecoride / Velectrix bikes).

Anyone have any idea how to remove the speed restrictions? The cable to the computer is 6 pin so the current USB adapters on the internet won't work.
I'm reliably informed a set of correct keypresses will get you into the secret menu but I am yet to work this out.

Thanks

Often having switched on one can hold the up/down buttons at the same time for about 10 secs, then a quick press of the on/off to toggle the menu. Using up or down to change values.
